Frequently Asked Questions
QWhat is a data URL?
A data URL is a URI scheme that embeds file content directly in the URL string as Base64-encoded data. Use it anywhere a file URL is accepted (src, href, background-image). Example: data:image/png;base64,iVBORw0KGgo…
QDoes Base64 encoding make images larger?
Yes. Base64 encoding increases the data size by approximately 33%. For large images this overhead becomes significant, so data URIs are best suited for small images like icons.
